Title: Refractory lining for steel desulphurizing vessel - is silica based material contg. silicon carbide, silicon, ferrosilicon, aluminium, and/or chromium
Inventor: HAYASHI TAKESHI
IPC: C04B35/14
Filed: 1976-08-10
Abstract: The refractory lining for mixers, casting ladles, or feed ladles is made from a mixt. of a refractory, siliceous, material, which is capable of expansion, and which contains 5-50 wt.% SiC, 2-30 wt.% Si, ferrosilicn, Si-Ca, Al and/or Cr in powder form, a few percent water and if required clay. The material pref. contains in addn. 1 wt.% (0.05-0.5 wt.%) alkali. The SiO2 content varies from 65 to 98 wt.% and is present as pyrophyllite ore, quartz, or sand.

Title: Fibre sheet esp. rock wool, prodn. - by pouring melt onto spinning disc, and sepg. annular stream of fibres to form open stream into which binder is injected
IPC: D04H1/4209
Filed: 1977-01-17
Abstract: A sheet of fibres is made starting from a melt fed onto the top of a disc rotated by a drive unit underneath the disc. The disc converts the melt into fibres blown by a current of air into an annular stream flowing past the drive unit and then spread out into a sheet. The annular stream of fibres is sepd. by a jet of gas to form an open stream into which a binder is injected from one or both sides to form the sheet. In the pref. plant, the melt is fed down a pipe onto a spinning disc surrounded by a ring of air jets which produce the annular stream. A slot jet then feeds a thin jet of gas in the opposite direction to the stream to "cut" or separate the fibres, which flow along a guice channel past injectors supplying the binder. Used esp. in the prodn. of rock wool starting from molten silicates, where the plant permits the easy injection of binders into the stream of fibres.
